When Remi was a puppy, Lauren taught him to put his head underwater and dive for things. It worked. He'll go to the bottom of the pool to get his ball. No fear!
This is the best example I could get, and its not the greatest as Jake jumps on him halfway thru his attempt to get his ball. But its funny none the less.
And Remi is a brat. He antagonizes Jake on a regular basis, then runs and hides.
